And H4 acetylation patterns across the DES locus and surrounding 500 kb region, we next sought to obtain a more detailed map of epigenetic status specifically across the DES LCR, as this constitutes a crucial regulatory element. Chromatin used for the microarray analysis was analysed by Q-PCR to assess enrichment for selected regions within DES and the DES LCR.The ENCODE region ENr331 which spans
